Data centres waste 90% of power drawn

Date: 17th October 2012

Data centres across the world use about 30 billion watts of electricity, about the same as the output of 30 nuclear power plants, with digital warehouses in the US accounting for between quarter to a third of that load, the New York Times Reported. Those are huge numbers for an industry that often puts forth an image of environmental friendliness.

Consider Apple’s soon-to-be-built research and development complex near its Cupertino, California, headquarters. The building, which will look something like a spaceship, will be entirely surrounded by a thick layer of trees and will be powered with its own energy centre that will run mostly off the grid. Yet in a year-long investigation, the NY Times found that “most data centres, by design, consume vast amounts of energy in an incongruously wasteful manner.”

Keysource says: There is no denying that data centres are consuming vast amounts of energy as the continuing consumerisation of IT and the growth of cloud computing creates demand. However, this increasing reliance on facilities to support critical IT and communications systems is also driving innovation within the marketplace that is contributing massively  to the reduction of energy usage. Free cooling is now widely recognised as an effective solution to enhance efficiency, reduce operating costs and lower Power Usage Effectiveness (PUE). As a result, the latest data centres are achieving high levels of performance and minimising environmental impact by optimising cooling that had traditionally represented a massive energy drain.
